17pie/12
Step-by-step explanation:
im sorry i don't have the pie sign
For a given function f(x) we define the domain restrictions as values of x that we can not use in our function. Also, for a function f(x) we define the inverse g(x) as a function such that:
g(f(x)) = x = f(g(x))
<u>The restriction is:</u>
x ≠ 4
<u>The inverse is:</u>

Here our function is:

We know that we can not divide by zero, so the only restriction in this function will be the one that makes the denominator equal to zero.
(x - 4)^2 = 0
x - 4 = 0
x = 4
So the only value of x that we need to remove from the domain is x = 4.
To find the inverse we try with the general form:

Evaluating this in our function we get:

Remember that the thing above must be equal to x, so we get:

From the two above equations we find:
b = 11
a = 4
Thus the inverse equation is:

C= 50y+20x
Where y is the number of boxes holding 50 pieces each and x is the number of boxes holding 20 pieces each.
Answer:
A. 50.24
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
f(4) = 3.14(4²) = 3.14×16 = 50.24
